Of what value is s = value()?

new topic     » topic index » view thread      » older message » newer message

I'd appreciate understanding, by way of basic examples, in what situations
the routine "value()" might be useful. At first I thought of it as a way of
converting one or more numeric character(s) to a number that could then be
used in computations - is that right? Then I realised it would convert a
character string to a sequence of corresponding ASCII values - when might
you capitalise on that capability? Finally I learnt that it would return
the same result for "36" as for "36P" - why might it be useful to do that?

Thank you
